Returns an iterator that refers to the location of an element in a set that has a key equivalent to a specified key. 複製 iterator find(const Key& key); const_iterator find(const Key& key) const; Parameters key The key value to be matched by the sort key of an element from the set...
find会挨个查找set,当到达set.end()时,也就是一个也没找到,返回end,即set.find(x) == set.end(),x为所查找的值 找到该数了,则返回该数的位置,所以可以用*(set.find(x))输出得到查找的该数。
FIND_IN_SET函数查找某个字符串是否在另外一个字符串中，如果存在，返回字符串第一次出现的位置序号；IN是查找某个字符串是否在另外一个字符串中，如果存在返回1，否则返回0 1、使用SELECT语句，查找字符串a是否在'b,c,d'中，调用FIND_IN_SET函数；由于字符串a不在'b,c,d'中，返回结果为0 2、接着，将'...
